Deep-set buoy gear

Deep-set buoy gear is an experimental gear type designed to target swordfish during the day. Recent trials indicate superior performance over shallow-set, nocturnal buoy gear, with higher target catch rates and lower shark bycatch. Development of a deep-set buoy fishery off the United States west coast must first address bycatch risk for bigeye thresher sharks and loggerhead sea turtles.
